[TIMOB-5106] Kitchensink: Crash after continued use of Kitchensink

Description: While testing Kitchensink, I started getting out of memory issues and experienced a crash shortly after. There was no log. A few hours later, I got a crash with a log. This may be difficult to reproduce and may be due to the architecture of the application. Logging for completeness. See attached crash log. Below find example of memory warnings prior to first crash: Mon Aug 22 15:26:05 unknown UIKitApplication:com.appcelerator.titanium[0xfbf4][82] : [DEBUG] loading: /var/mobile/Applications/7A39CEBA-94DF-4299-B9D9-978EC89C50A5/KitchenSink.app/examples/table_views.js, resource: examples/table_views_js Mon Aug 22 15:26:05 unknown configd[25] : jetsam: kernel memory event (91), free: 711, active: 1599, inactive: 1956, purgeable: 1655, wired: 9240 Mon Aug 22 15:26:05 unknown SpringBoard[28] : Received memory warning.
